The expression 3w^2 represents the area of the garden since the length l is equal to 3w
A rectangle is a 2D shape that has 4 sides and angles. The formula for calculating the area of a rectangle is expressed as:
Area = length * width
If the length of a rectangular garden is three times its width w, hence;
l = 3w
Given the following
A = 300 square meters
Substitute the given parameters into the formula
A = 3w(w)
Substitute the area
3w^2 = 300
Hence the expression 3w^2 represents the area of the garden since the length l is equal to 3w
